Describe the bug

I made two small changes (one to one model and one to another model). I ran npm run amplify-modelgen. When I run amplify push everything looks like it works except that I see the output:

⠙ Updating resources in the cloud. This may take a few minutes...Successfully generated models. Generated models can be found in /Users/emmafass/ringside-pro/src
✔ Code generated successfully and saved in file src/API.ts
Failed to create models in the cloud: Modelgen job creation failed
✔ All resources are updated in the cloud

I first saw this error after I tried an amplify push and it asked me if I want to upgrade my node version in some of the template files of the functions I created. It suggested doing this in a dev environment as it may cause some issues. I went forward with it in dev and then saw the Failed to create models in the cloud: Modelgen job creation failed error.

To confirm that the models were not correctly updated in the cloud, I want to AppSync and checked my schema. The changed models were still in their old forms.

I tried making a minor change to my schema. Then I ran amplify push again. Same output with the same error.

Expected behavior

Expect the changes I made to be pushed to the cloud.

Reproduction steps

1. Make a change to a model in schema.graphql
2. Run npm run amplify-modelgen
3. Run amplify push
